Yesterday I saw a display of telescoping anodized Al flagpoles that I
wondered about as possibly being suitable for use as a shunt-fed
vertical antenna at home and for Field Day or other portable operations.|
These are available in 16', 20' and 25' models and are designed to drop into a mounting socket embedded in the ground. The sections lock into place by means of spring-loaded pins.
The contraindications for using such a device as an antenna are the difficulty of
(a) getting a sufficiently good electrical contact between the sections
(b) finding a suitable feed point without having to scrape off the anodizing at many different points in search of a position that works.
